DETAILED DESCRIPTION

FIG. 1 illustrates an example search results page 150 provided by an example prior art search system 140. The search system 140 is an example of an information retrieval system in which the systems, components, and techniques described below can be implemented.

A user device 110 can be coupled to the search system 140 through a data communication network 130. In general, the user device 110 transmits a query 120 over the network 130 to the search system 140. The search system 140 identifies indexed resources that satisfy the query 120 and generates a search results page 150. The search system 140 transmits the search results page 150 over the network 130 back to the user device 110 for presentation to a user. Generally, the user is a person.

The user device 110 can be any appropriate type of computing device, e.g., a server, mobile phone, tablet computer, notebook computer, music player, e-book reader, laptop or desktop computer, PDA (personal digital assistant), smart phone, or other stationary or portable device, that includes one or more processors for executing program instructions and memory. The user device 110 can include computer readable media that store software applications, e.g., a browser or layout engine, an input device, e.g., a keyboard or mouse, a communication interface, and a display device.

The network 130 can be, for example, a wireless cellular network, a wireless local area network (WLAN) or Wi-Fi network, a Third Generation (3G) or Fourth Generation (4G) mobile telecommunications network, a wired Ethernet network, a private network such as an intranet, a public network such as the Internet, or any appropriate combination of such networks.

The search system 140 can be implemented as computer programs installed on one or more computers in one or more locations that are coupled to each other through a network, e.g., network 130. The search system 140 includes an index of resources and a search engine.

When the query 120 is received by the search system 140, a search engine identifies resources that satisfy the query 120. The search engine will generally include an indexing engine that indexes resources, e.g., web pages, images, or news articles on the Internet, and a ranking engine to rank the resources that have been identified. The indexing and ranking of the resources can be performed using conventional techniques.

The search system 140 responds to the query 120 by generating a search results page 150, which is transmitted over the network 130 to the user device 110 in a form that can be presented on the user device 110, e.g., as displayed in a web browser on the user device 110. For example, the search results page 150 can be a markup language document, e.g., HyperText Markup Language or eXtensible Markup Language document. The user device 110 renders the document, e.g., using a web browser, in order to present the search results page 150 on a display device. The user device 110 can also display the terms of the query in a query box 152 or “search box”, located, for example, on the top of the search results page 150.

The search results page 150 generally presents multiple search results 160, 170, and 180. Each of the presented search results can include titles, text snippets, images, links, reviews, or other information. For example, the search result 160 includes a title 161, a snippet 162, and a display link 163.

Each search result 160, 170, and 180 is displays a link to a particular resource. Selection of one of the search results 160, 170, or 180, e.g., by a click, causes a display program running on the user device 110 to navigate to the resource associated with the search result identified by the display link 163.

FIG. 2 illustrates an example search results page 250 that includes secondary music search result links 275 a-c. The search results page 250 can be provided by a search system when an identified search result is linked to a music web page that provides markup language music data.

The search results page 250 includes search results 260, 270, and 280. Search result 270 includes a title 271, a snippet 272, and a display link 273. Search result 270 also includes secondary music search result links 275 a-c. Selection of a secondary music search result link causes a display program running on the user device, e.g., a web browser, to navigate to a music resource. Music resources include resources from which music content can be accessed. The music content can include embedded, streaming, or downloadable audio and video. For example, selection of the secondary music search result link 275 a “No Time Like Now” causes a display program running on the user device 210 to navigate to a resource where streaming audio of the song “No Time Like Now” can be accessed by, e.g., a user of the user device 210.

The provided secondary music search result links can include any of a number of music data elements, including a title, artist name, album name, duration, year of release, a link to an image of album cover art, keywords, awards, ratings, relevant URLs for, e.g., artist websites, in addition to many others. Each illustrated secondary music search result link 275 a-c includes the song duration 277 and album name 278. Each illustrated secondary music search result 275 a-c also includes an icon that identifies the type of file available from the corresponding music resource. For example, secondary music search result link 275 b includes an icon 276 b indicating that the available data is video data. Secondary music search result link 275 c includes an icon 276 c indicating that the available data is streaming audio data.

Music data presented in secondary music search result links can be obtained from web pages that serve resources including markup language music data. In some implementations, the markup language music data is not presented or rendered on the user device, and is rather served on web pages only to be parsed and used by the search systems, e.g., search system 240.

A markup language is a convention for annotating text by syntactically distinguishable elements called tags. Tags identify a property of the marked-up text. Tags can themselves include further data called attributes. The following example XML snippet identifies a song title and artist with corresponding tags:

<song>   <title>No Time Like Now</title>   <artist>John Example Band</artist> </song>

Music data can also be specified by other kinds of markup, including HTML5 microdata in HTML documents. HTML5 microdata can be used to annotate text, on a website, for example, with name-value pairs that are referred to as properties. For example, a song name can be specified by the following example HTML5 code:

<div itemprop=″song″ itemscope>   <span itemprop=″title″>No Time Like Now</span>   <span itemprop=”artist”>John Example Band</span> </div>

The first itemprop attribute indicates a property of “song” for a particular document division identified by the “<div>” tag. The itemscope attribute indicates the beginning of a group of name-value pairs. Each name-value pair is specified by further itemprop attributes, including the name “title” and the value “No Time Like Now,” as well as the name “artist” and the value “John Example Band.”

A search system can parse the markup language code, e.g. XML or HTML5, to obtain music data provided in a particular resource, e.g. a web page. The search system can then store the music data, including, for example, the song title and artist, as appropriate for generation and presentation as secondary music search result links.

FIG. 3 is a flow chart of an example process 300 for presenting secondary music search result links in response to a search query. The process 300 can be implemented by one or more computer programs installed on one or more computers. The process 300 will be described as being performed by a search system, for example, the search system 240 of FIG. 2.

The system receives a search query (310). The search query can, for example, be received over a network from a user device.

The system obtains search results (320), for example, from a search engine subsystem. The search engine subsystem can identify resources that satisfy the search query from a database of indexed resources. Each search result identifies a resource having a particular network address, e.g., a URL.

The system determines that a particular search result will include secondary music search result links (330). The system can determine that a particular search result should include secondary music search result links from a previously built and maintained database of data from music web pages that have provided markup language music data. The database can store a set of key-value pairs, where the key is the network address of a resource, and the value is one or more elements of corresponding music data provided by the resource. The database of music data can be built and updated by crawling and parsing resources on a network, e.g., the Internet, by an indexing engine of a search engine, and organizing the data in a suitable form of database. If a resource identified by a particular search result has a corresponding entry in the database of music data, the system can determine that the particular search result will include one or more secondary music search result links that include at least some of the music data stored in the corresponding database entry.

The system can also apply additional criteria for determining whether the particular search result will include secondary music search result links. For example, the system can limit the number of search results on a search results page that include secondary music search result links. Thus, if a maximum number of search results that include secondary music search result links already exist, the system can omit secondary music search result links from a particular search result, even if the particular search result would otherwise include secondary music search result links.

The system can also determine not to present secondary music search result links when other types of secondary search result links are present on the search results page. For example, the search system can determine to present secondary search result links for categories other than music, for example, events and people. If a particular search result or other search results on the search results page already include other types of secondary search result links, the system can omit secondary music search result links from the particular search result even if the particular search result would otherwise include secondary music search result links. Alternatively, the system can determine to present secondary music search result links when search results identifying rich media, e.g. videos or streaming audio, are presented on the search results page.

The system can also impose a quality threshold on a particular secondary music search result link before including the particular secondary music search result link with a search result. For example, a relevance measure of a resource identified by a secondary music search result for a particular query can be taken into account when determining whether the secondary music search result link will be included. If the measure does not satisfy a threshold, the system can omit the secondary music search result link for the search result. Similarly, the system can also impose a threshold on the search result itself. If a particular search result does not satisfy a quality threshold, the system can omit the particular secondary music search result link from the search result.

Other quality thresholds can optionally also be used. For example, the system can also determine a measure of popularity of music content in a music database, for example, or a view count of particular videos. The system can then generate secondary music search result links corresponding only to songs that satisfy a popularity threshold. The popularity can also be determined using query popularity. For example, if a query does not satisfy an overall popularity threshold, the system can determine not to present any secondary music search result links in response to the query.

The system can also determine to present secondary music search result links only when the query is a music query. In some implementations, the system determines that the query is a music query by checking a whitelist of music queries. In other words, if the query does not appear on the whitelist of music queries, the system can determine not to present secondary music search result links.

The system can also determine whether the query is a music query using one or more signals. For example, the system can analyze query logs that store previously-received queries and search results provided in response. The system can analyze each of a number of the top-ranked search results, e.g., top 10 results, from the query logs to determine whether the search result is a music search result. A search result can be classified as a music search result if the search result identifies a resource from which music content can be accessed. The system then determines whether a threshold number or fraction of the top-ranked search results are music search results. If not, the query is not considered a music query. The system can also provide the signals to a linear classifier that has been trained using supervising machine learning to determine whether the query is a music query from the signals. One example signal is a classification of the terms of the query. For example, the system can submit the terms of the query to a classifier that classifies the terms according to a taxonomy. Another example signal is whether the query returns results in a list of known music search results.

The system generates a search results presentation including one or more secondary music search result links (340). The system can generate for each search result a title, a snippet, and a display link. The system can further generate secondary music search result links for a particular search result linked to a resource that has a corresponding entry in the database of music data. Each secondary music search result link can be linked to a respective music resource from which an audio or video file, for example, can be accessed.

The system provides the presentation of search results in response to the search query (350). The system can transmit the search results presentation as a document over a network to the user device for presentation on a display device by, for example, a web browser running on the user device.

Generally, a processor will receive instructions and data from a read-only memory or a random access memory or both. The essential elements of a computer are a processor for performing actions in accordance with instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto-optical disks, or optical disks. However, a computer need not have such devices. Moreover, a computer can be embedded in another device, e.g., a mobile telephone, a personal digital assistant (PDA), a mobile audio or video player, a game console, a Global Positioning System (GPS) receiver, or a portable storage device (e.g., a universal serial bus (USB) flash drive), to name just a few. Devices suitable for storing computer program instructions and data include all forms of non-volatile memory, media and memory devices, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks.
